Appeal No. 1996-2198
Application 08/077,506
to said table, said plurality of time sequences of feature
vectors being produced in response to a plurality of speech
signals; and first forming means for forming, in response to
said plurality of time sequences of feature codes, a state
transition probability in a state transition network and a
probability distribution of occurrence of the feature codes in
each state in said state transition network;
wherein the improvement comprises:
function generating means, connected to said table and
said first forming means, for generating an approximate
continuous probability density function said approximate
continuous probability density function approximating said
probability distribution of occurrence of the feature codes in
each state in said state transition network, said code vectors
being used as parameters in said approximate continuous
probability density functions; and
second forming means, connected to said first forming
means and said function generating means, for forming as a
reference pattern for said plurality of speech signals a
combination of said state transition probability distribution
and said approximate continuous probability density function.
Appellants treat claims 3-5 as standing or falling with
claim 1 and argues claim 2 separately (Brief at 15).
